Welsh Bicknor

Welsh Bicknor (Welsh: Llangystennin Garth Brenni) is an area in the far south of the county of Herefordshire, England. It lies within a loop of the River Wye and covers 8,502 acres (13.3 sq mi).

The area was historically a detached parish (exclave) of the Welsh county of Monmouthshire. In 1844, it was transferred to the English county of Herefordshire. It is adjacent to English Bicknor and Lydbrook, which are part of Gloucestershire.
